Description
Technical field
The invention belongs to building structure connection area, and in particular to prefabricated post-overlapping in a kind of assembled RC frame shear structures
Beam top story exterior joints connection method.
Background technology
Traditional cast-in-place building refers to carry out the construction such as reinforcing bar colligation, formwork supporting plate, casting concrete at the construction field (site) to form
Building.The past for quite a long time, cast-in-place building solves personnel's employment etc. to receiving surplus rural labor force of China
Serve positive, current cast-in-place mode still occupies absolute main flow in China's construction.But, it is cast-in-place for a long time to build
Build and be widely present in constructing situ wet operation amount greatly, labour's input amount is big, and labor strength is high, poor working environment, mould
The input amounts such as plate, scaffold are big, turnover utilization rate is low, mechanized construction low degree, construction safety hidden danger and Frequent Accidents, relatively
The thorny problem such as work efficiency is not high and job site largely produces airborne dust, noise pollution, building waste many.These cast-in-place buildings
Congenital drawback is incompatible with the trend of the current construction industry development of China.
Assembled architecture is, in plant produced, to be assembled building subassembly and component and fitting at the construction field (site) and be formed by connecting
Building.It with modern science and technology is support that the construction of assembled architecture is, with industrialized production as means, with engineering
Mesh management innovation is core, and building products production overall process is coupled integral by extensive utilization information technology, intelligent environment protection technology
Change the structural system of industrial chain, assembled architecture can economize on resources and be polluted with the energy, reduction, effectively improves labor productivity,
Improve construction quality etc..The house for meeting China " 13 " national development stage " energy and land saving " and " structure industrial system " is produced
Industry guiding theory, with significant economic benefit and social benefit.The current desalination along with China human mortality bonus, it is of the right age to build
The reduction of industry number of employees is built, development assembled architecture is brought into schedule in good time.
Assembled architecture presses structural system, is broadly divided into assembled frame-shear structure, fabricated shear wall structure, assembled frame
Frame-shear wall structure etc..Wherein first two structural system is relatively more in the research of China, and both at home and abroad to assembling frame-
The research of shear wall structure is also relatively fewer, and existing research is concentrated mainly on theoretical and numerical simulation aspect, wherein H. A.
D. Samith Buddika etc. have carried out theoretical research based on Opensees softwares to assembled frame shear structure.Dionysios
Bournas etc. has carried out pseudo to 1 three layers of assembled frame shear structure model, have studied structural model different parts,
Damaged situation of the node of multi-form under geological process.Majid Divana etc. with nonlinear static force method to difference across number and
The assembled frame shear structure of floor height has carried out theoretical research.Current developing rapidly in China, assembled with building industrialization
The application of frame shear wall structure is increasing, therefore is necessary to further investigate it.
At present, the common practice to shear wall position in assembled RC frame shear structures is using traditional complete cast-in-place mode
Shear wall is built, this is mainly based upon in frame shear wall structure, shear wall as main lateral resistant member, in earthquake
In undertake most horizontal force, while shear wall is destroyed at first as the first line of defence in earthquake, thus shear wall from
The anti-seismic performance quality of body is most important.For the requirement of shear wall aspect of performance, the present patent application scheme proposes a kind of dress
With prefabricated post in formula RC frame shear structures-composite beam top story exterior joints connection method.
